Thank you for posting in the forums. I have seen this issue once already and is seems to be stemming from an issue with the .net framework, we would want to uninstall .net with this link: http://www.logos.com/media/tech/dotnetfx_cleanup_tool.zip.
Download the zip and open it. Run the cleanup_tool program.
Have the drop down set to .NET Framework - all versions, then click Cleanup Now.

This is a crash trying to play the startup sound. Unfortunately, I can't think of a workaround to disable the startup sound without launching the application. (Do you have a second computer? If so, you may be able to turn off the "Play Sounds" setting on that machine, and have it sync to this machine with the problem.)

We'll add a fix in the next 5.0 service release.

Is this something that could be changed in the registry, or does Logos not store the "Play Sounds" setting in the registry? This is a setting that I would think people wouldn't want synced between their different machines. I personally keep startup sounds off for all my apps all the time, but I could imagine someone who doesn't mind it at home but doesn't want it sounding at the office where it might annoy others.

Running the .NET uninstall, restarting then running the downloaded did not solve the problem. I re-installed all the frameworks, used Microsoft fix-it finding no errors and repairing various packages attempting to run logos 5 along the way with no avail.

I am also a .NET developer, don't have too much time to poke around but will try some things out. Wife was visiting (Mobilized Army reserves) so I spent time with her rather than playing on the computer this weekend.

I have a Windows 7 N x64 bit MSDN running with minimal install including Office 2010. This is a fresh install as of approx 2.5 weeks ago when I put in new drives RAID 1 config.

Logos 4 was working fine and no problems with any other apps I tried to run either. Not sure how Logos 5 is initializing the Wave player.

Running WIN 8 in Virtual PC (VMWare) ant it loads and plays sound with my default device. However, I don't want to download all 13+ GB of resources from my primary account so I logged in with a secondary account.
